// Connect

    echo 'Error When Connect SQL!<br />';
    die('Could not connect: ' . mysql_error());
}

// Create Database
if(mysql_query("CREATE DATABASE Person_Lists",$con)){
    echo "Database created";
}else{
    echo "Error creating database: " . mysql_error();
}

// Select Database
mysql_select_db("Person_Lists", $con);

// Create table in Person_Lists database
$sql = "CREATE TABLE Persons
(
PersonID int NOT NULL AUTO_INCREMENT,
PRIMARY KEY(personID),
FirstName varchar(15),
LastName varchar(15),
Age int
)";
//mysql_query($sql,$con);

mysql_query("INSERT INTO Persons (FirstName, LastName, Age) VALUES ('Fisher', 'AA', '20')");
mysql_query("INSERT INTO Persons (FirstName, LastName, Age) VALUES ('Fisher', 'BB', '40')");
mysql_query("INSERT INTO Persons (FirstName, LastName, Age) VALUES ('Fisher', 'CC', '30')");

$result = mysql_query("SELECT * FROM Persons");
